Highlights |
• | NKG2D CAR-T exhibits a good killing effect on endometrial high cytotoxicity against cervical cancer tumor cells both in vivo and in vitro . |
• | NKG2D CAR-T has no obvious killing effect effects on normal tissue cells and has tissues, suggesting a good safetysafety profile. |
Abstract |
Cellular immunotherapy, including chimeric antigen receptor (CAR) modified T cell therapy, has been regarded as one of the most potential antineoplastic drugs for hematological malignancies and solid tumor. However, due to lacking the suitable target, there is no CAR-T drug had been appoved by FDA for the treatment of cervical cancer, one of the most malignant cancers for women. In current study, we designed a NKG2D CAR-T targeting NKG2DL. The NKG2D CAR-T exhibited high-efficient anti-tumor capacity for NKG2DL positive cervical cancer cell line in vitro. In addition, the amount of cytokines secreted from CAR-T cells have had significantly enhanced after co-cultured with NKG2DL positive tumor cell in vitro. In vivo, NKG2D CAR-T cells presented a robust capacity of significantly suppressing tumor growth. Moreover, there was no obvious off-target toxicity after NKG2D CAR-T infusion. Taken together, NKG2D CAR-T showed excellent therapy effect for cervical cancer and might be used as a novel cellular therapeutic agent for treating cervical cancer.
